Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed July 3-, 1916. semi 1%. 107,412.

To all whom it may concern:

Beit known that I, HENRY Gr. NnwELL, a citizen of the United States, residing at Le Raysville, in the county of Bradford and State of Pennsylvania, have invented a new and useful Battery-Saver for Telephones, of which the following is a specification.

The present invention is a battery saver for telephones, and aims to provide a novel and improved stop or catch applicable to telephone instruments generally, and coiiperable with the receiver or switch hook for holding it in intermediate position, with the battery transmitter and outside noises cut out, when the receiver is lifted from the hook.

The objects of the invention are made apparent by noting conditions prevailing in telephone practice, as follows In local battery telephone service, the depletion or weakening of the battery is. decidedly detrimental to strong and cleartransmission and good service. This depletion of battery our rent, on party lines especially, results from eaves-dropping or listening in, and it also results legitimately from the time consumed in waiting for the line or distant connec In noisy places there is also great gain to hearing if the transmitter and outside noises are cut out on listening and only cut in while talking. Long distance hearing is much improved and the local service also, as in party line service listening-in along the line introduces the nuisance of foreign noises,- such as the crying of childreinetc. The aforesaid losses of battery power and other disadvantages are largely responsible for poor service and considerable expense, not only for battery cells, but for livery hire and the time of the electriciaii in putting in newcells. Because of the foregoing Ob ections, this invention was conceived to savethe battery current and improve the service:

It is known that clumsy knife switches, push buttons, etc, have been used or resorted to, for the saving of battery current, but are more or less inconvenient and re quire special wiring and an electrician to install them properly, and are not entirely satisfactory, While certainly not universally applicableor convenient in use.

It is the primary object of the invention to meet the needof a deviceof the present character; using adevice which is simple, convenient, and etfieient in nee,- and providing a complete and attractive mail order specialty for telephones generally, the device being easily and quickly attached and accurately adjusted. by any one of average intelligence. The present device is not only convenient in use, and natural in operation, but is perfectly reliable and not likely to get out of order with inexperienced users.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed Without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 isan elevation of the device as applied to a telephone set, a portion only of the set being illustrated, and portions being illustrated diagrammatically- Fig. 2 is another elevation of the device, looking at right angles to the line of View in Fig. 1.

' In Fig. 1,- a fragmentalportion of a Wall telephone set is depicted, the same including the 0x or casing 1 and receiver hook or fork working within a'slot in one 'wall. ofthe box or cabinet 1,; A spring contact 3 is connected with the hook 2 to be moved thereby, and forms'a part 'ofa circuit 4. The primary or local circuit 5 includes the battery 6' and transmitter 7 and has the terminal springzcontactsfi and 9 which when they are brought together" close the primary circuit).

The contacts 3, 25 and 9 are normally separated when. the receiver hook is lowered, and when the receiver hook is in intermediate position, the contact 3 engages the contact 8, while when the receiver hook is completely raised, the contact 3 raises the contact 8 with it against the contact 9. It is the function of the present device to hold the receiver hook in intermediate position whereby the receiver can be held to the ear for listening in on the line, for any purpose whatever, without the primary or local circuit 5 being closed, thus avoiding the wastage of current, and nuisance of outside noises, and with the advantage of cutting in and out instantly, simply and conveniently.

The present device as illustrated in Figs. 1, 2 and 3, embodies a pendant arm 10, formed of wire or other suitable stock, and formed at its upper end with coils 11 providing a bearing through which a nail or other pivot element 12 can be inserted to be driven into or otherwise engaged with the box 1 for pivotally hanging the arm 10 upon. the out side of the box adjacent to the receiver hook, as clearly seen in Fig. 2.

Mounted adjustably on the arm 10 is a stop constructed of wire or other suitable material, and formed with close fitting coils 13 having a vertical axis, the wire being formed with a depending loop shaped handle 14 at the lower end of the coils 13, and said coils being interiorly threaded and be ing screwed upon the arm 10 which is also threaded. The coiled nut or sleeve 13 is rovided at that side adjacent the receiver hock 2 with anoutstanding loop 15 overhanging the receiver hook, and providing the stop proper or catch, which is provided with the lower shoulder 16 adjacent the coiled nut 13 and the inclined or cam por tion 17 at the outer end of the shoulder 16. The coiled nut 13 is provided with an out" standing loop-shaped finger piece 18, which in being disposed adjacent to the box 1, will prevent the nut 13 being unscrewed acci dentally while the arm 10 is in place. The coiled bearing 11 has a horizontal axis perpendicu'lar with the side wall of the box 1 whereby the arm 10 is swingable in a plane parallel with the box to and from the receiver hook 2. In one position of the arm 14, as seen in Fig. 2, the cam portiorr'l'i' is above the receiver hook 2, whereas if the arm 10 is disposed on the line m-rc'in Fig. 2, the shoulder 16 will hoover the receiver hook. The coils 11 provide an excellent broad bearing for the arm 10., and the coils 13 provide a relatively long threaded sleeve or nut which may have any desired degree-of tension for gripping the arm or rod.10.. The arm 10 can be readily attached to-the box. or other support'of the cabinet at the proper point, whereby the arm will swing- -away from the receiver hook by gravityto remove the stop or catch loop 15 from over the hook, either partially or completely. When the arm 10 is detached, it can. be readily rotated with respect to the sleeve or nut 13 for adjusting the stop, whereby to properly hold the receiver hook in intermediate position when the stop is moved over the hook with the receiver ofi.

To provide a manually operated lock out and automatically restored device, the arm 10 is supported, as seen in Fig. 2, with the cam portion 17 normally over the receiver hook 2. Now, when a person desires to listen in on the line, as when waiting for a party called, or when listening for any purpose, when the receiver is taken off of the hook, the thumb or one finger of the hand (usually the left hand) which removes the receiver can be readily and naturally brought against the handle or thumb piece 14:, to swing the arm toward the receiver hook, at the same time that the receiver is removed, thus bringing the shoulder 16 over the hook, and the hook in bearing upwardly against the shoulder 16 will prevent the hook from being completely raised. The hook will therefore he held in intermediate position, with the circuit 5 open. This. saves the battery current and also cuts out the transmitter thereby avoiding unnecessary and troublesome noises on the line.- Ordinarily,- when the receiver hook is raised without touching the present attachment, the receiver hook 2 in engaging the cam portion 17 will deflect the stop out of the way. For the repeated cut ting in and out of the battery and transmitter, as in exacting long distance conversation or other severe conditions, the horizontal thumb and finger piece 18 can be readily raised and lowered, or moved backward and forward alternately, which can be readily done by the right hand. Thus, when the arm 10 is moved away from the receiver hook, the receiver hook is permitted tomove to raisedposition, and, when the arm is moved toward the receiver hook, the cam portion 17 will depress the receiver hook to intermediate position, this operation. being easily and quickly accomplished.

A second method of using the device. is to position the arm 10, on the line 1ED in Fig. 2, whereby the shoulder 16 is normally over the receiver book 2, thus providing an automatically and normally operative lockout and manually restored device, since when the receiver is taken off of the hook, the hook will strike the shoulder 16, thus hold in}: thereceiver hook automatically in intermediate position, and the arm 10 must be moved away from the receiver hook, to per: mit the receiver hook to move to its raised pO Slt QIL.
